Make all visual tools support selecting and manipulating multiple visual features at once, allowing multiple lines to be moved at once, entire vector clips to be translated, etc. Controls: - Left click: Select control clicked control only - Ctrl-left click: Add/remove control to selection - Drag control (with or without ctrl): Move all selected controls, after setting/adding to selection if target is not in the selection - Click on no control: Clear selection Lots of little stuff to fix still. Updates #513. Originally committed to SVN as r4322.
